HUB-ATTACHING DEVICE.

SPECIFICATION forming part of Letters Patent No. 636,700, dated November 7, 1899.

Application filed July 10, 1899. Serial No. 728,374. (No model.)

To allwhom it may concern:

Be it known that I, DANIEL WARNER,-a citizen of the United States, residing at Bronson, in the county of Branch and State of Michigan, have invented a 'newand-useful Hub- Attaching Device, of which the following is a specification.

This invention relates to hub-attaching devices, and has for its object to provide improved means for facilitating the removal of the wheel from the axle-spindle.

To this end the present invention consists in the combination and arrangement of parts,

as will be hereinafter more fully described, shown in the accompanying drawings, and particularly pointed out in the appended claims, it being understood that changes in the form, proportion, size, and the minor details of construction may be made within the scope of the appended claims without departing from the spirit or sacrificing any of the advantages of the present invention.

In the drawings, Figure 1 is a side elevation of an axle and the box thereof having the presentinvention applied thereto. Fig. 2 is a longitudinal sectional View thereof. Fig. 3 is a transverse sectional view taken on the line 00 m of Fig. 2. Fig. 4 is a detail perspec tive view of the adjustable wrench for facilitating the removal of the wheel.

Corresponding parts in the several figures of the drawings are designated by like characters of reference.

Referring to the accompanying drawings, 1 designates a portion of a common or ordinary axle having the usual spindle 2, which is provided near its inner end with an integral annular flange or shoulder 3.

Mounted to turn on the spindle is an axle.- box 4:, having its outer end open and interiorly threaded and closed by means of a removable screw-plug 5, which prevents ingress of dirt or other foreign matter into the bearing and also prevents loss of the lubricant. At the opposite end of the box the bore thereof is enlarged, so as to receive the annular flange or shoulder 3 of the spindle and provide an annular shoulder 6,en gaging against the outer face of the shoulder or flange 3. The remaining portion of the enlarged part of the bore of the box is threaded to receive a hollow nut 7, which loosely embraces the inner end of the spindle and abuts against the adjacent inner face of the annular flange or shoulder 8, whereby the box may turn upon the'spindle with the wheel, but is prevented from being displaced longitudinally from the spindle by reason of the inner end of the nut abutting against the adjacent face of the flange or shoulder of the spindle. This nut is provided with an annular flange 8, which covers the inner end of the box, so as to preventingress of foreign matter at the inner end of the hub, and is provided exteriorly of the flange 8 with a wrench-head 9.

Slidable upon the upper face of the axle and adjacent to the inner end of the spindle is a wrench 10, comprising a flat metal plate having opposite longitudinal pendent flanges 11, which embrace opposite sides of the axle, so as to prevent lateral displacement of the wrench and guide the latter in its slidable movement. A longitudinal slot 12 is provided intermediate of the opposite sides of the plate, and a thumbscrew 13 passes loosely through said slot and into a threaded opening 14, formed in the upper side of the axle. The head 15 of the thumb-screw overlaps the opposite edges of the slot 12, as clearly indicated in Fig. 3, so that the wrench may be efiectively clamped upon the axle. At the forward end of the plate 10 there is provided an upwardly-extending shoulder 16, and projecting forwardly therefrom is a flange 17, provided at opposite ends with downwardly and outwardly flared shoulders 18, forming a wrenchj aw which is adapted to embrace the wrenchhead 9 of the nut 7, as clearly shown in Figs. 2 and 3. Normally the wrench is carried out of engagement with the nut -7, as shown in Fig. 1, so that the axle-box and said nut may turn with the Wheel. When it is desired to remove the wheel, the wrench is moved forward into engagement with the nut 7, as indicated in Fig. 2, whereby said nut is fixed upon the axle and prevented from turning thereon, after which the wheel is turned in a reverse direction, thereby unscrewing the box from the nut 7 and permitting of the wheel being removed from the spindle. To replace the wheel, the box is slipped upon the spindle and the wheel turned in a forward direction, so as to screw the box upon the nut 7, and then the wrench 10 is disengaged from the nut, whereby the wheel is free to turn upon the spindle in the usual manner.

From the foregoing description it will be apparent that the present form of wrench may be engaged with and disengaged from the hollow nut in a convenient and effective manner, and may beheld outof engagement therewith in a positive manner, so as to prevent accidental locking of said nut upon the axle.

Vhat- I claim is- 1. The combination with an axle-spindle having an annular flange or shoulder near the inner end thereof, of an axle-box having the inner end of its bore enlarged to receive the flange or shoulderof the spindle, and also internally threaded, a hollow nut loosely fitting the axle and screwed into the inner threaded end of the axle-box, and a wrench, comprising a Hat plate slidable longitudinally upon the axle, and having a wrench-jaw for engagement with the hollow nut, substantially as and for the purpose set forth.

2. The combination with an axle-spindle having an annular flange or shoulder near the inner end thereof, of an axle-box having the inner end of its bore enlarged to receive the flange or shoulder of the spindle, and also internally threaded, a hollow nut loosely fitting the axle and screwed into the inner threaded end of the axle-box, and a wrench, comprising a flat plate having opposite longitudinal flanges loosely embracing opposite sides of the axle, a longitudinal slot, an outwardlyprojecting shoulder at the forward end of the plate, a flange extending forwardly from the shoulder and provided at opposite ends with divergent shoulders, and a thumb-screw passing loosely through the slot in the plate and engaging a threaded opening formed in the axle, substantially as and for the purpose set forth.'

In testimony that I claim the foregoing as my own I have hereto affixed my signature in the presence of two witnesses.

DANIEL WARNER.
